SPRING-WHEEL.

Application filed. June 14, 1913.

To all whom it may concern:

Be it known that I, CHARLES V. BRANDT, a citizen of the United States,residing at Richmond, in the county of Henrico and State of Virginia,have invented certain new and useful Improvements in Spring- Wheels, ofwhich the following is a specification, reference being had to theaccompanying drawings.

This invention relates to certain new and useful improvements in springwheels of that character designed for use upon automobiles and othervehicles, the primary object of the invention residing in the provisionof improved means for mounting the inner ends of the springs in thewheel hub.

The invention has for another and more specific object the provision ofa plurality of springs of curvilinear form arranged between the rim andhub of the wheel, the wheel hub consisting of spaced plates provided atintervals with notches or recesses, said springs having formed upontheir opposite edges and adjacent their inner ends, shoulders forengagement in said notches, and sleeves formed upon the inner ends ofthe spring plates to receive bolts extending through the hub plates.

The invention has for a further object to provide a spring wheel ofsimple and durable construction, whereby vibration is practicallyeliminated, thus relieving the engine and all other parts of the vehicleof considerable strain and materially conducing to the comfort of theoccupants of the vehicle.

With the above and other objects in view, as will become apparent aS thedescription proceeds, the invention consists in certain constructions,combinations and arrange ments of the parts that I shall hereinafterfully describe and claim.

For a full understanding of the invention, reference is to be had to thefollowing description and accompanying drawing, in which Figure 1 is aside elevation of a spring wheel embodying the preferred form of myinvention. Fig. 2 is a section taken on the line 22 of Fig. 1. Fig. 8 isa section taken on the line 33 of Fig. 2. Fig. 4 is a detail perspectiveview of one of the spring plates.

Referring in detail to the drawing, 5 designates the hub of the vehiclewheel which includes a body having spaced annular plates or flanges 6.

Serial No. 773,714.

7 designates the rim of the wheel upon which a tire of any approvedconstruction, but preferably of solid rubber, is adapted to be secured.

Between the hub and rim of the wheel, a plurality of curved springplates 8 are arranged. Each of the plates is of a width equivalent tothe distance between the outer faces of the hubplates or flanges 6 andis secured at its outer end to the wheel rim by means of a plurality ofbolts 9, the heads of which are countersunk in the outer face of therim. It will be understood that any desired number of these fasteningbolts may be employed. The inner ends of the spring plates are reducedin width, as indicated at 10, to provide the shoulders 11 on oppositeedges thereof. These reduced inner ends of the spring plates are adaptedto be arranged between the opposed faces of the hub flanges and theshoulders thereon engaged in peripheral notches or recesses 12 formed insaid flanges. Upon the extremity of the reduced end 10 of each springplate a cuff or sleeve 13 is formed. Through these sleeves securingbolts 14 are adapted to be inserted, said bolts extending throughopenings provided in the hub flanges. The spaces between the inner endsof the spring plates and the opposed faces of the hub flanges arepreferably closed by means of the plates 15, integrally formed on theedges of the flanges 6, whereby the collection of dirt or other foreignmatter in said spaces is prevented.

It is to be observed that the rim 7 on its under surface adjacent itsmarginal portion is provided with an annular shoulder 7 with which theadjacent edge portions of the plate which are secured thereto areadapted to snugly contact in order to serve as an edective means toprevent such plates from lateral movement or distortion.

From the foregoing, it is believed that the construction and severaladvantages of my improved spring wheel will be clearly and fullyunderstood. By the provision of the shoulders on the inner ends of thespring plates for engagement in the recesses provided in the diskflanges, the fastening or securing bolts are relieved ofconsiderablestrain. while the inner ends of the spring plates areeffectually held against any circumferential movement with relation tothe wheel hub.

My improved Wheel structure as a whole is extremely strong and durable,and owing to its simplicity, it will be appreciated that the same can beproducedat small manufacturing cost.

As the provision of the series of spring plates between the wheel huband rim serves to absorb all vibration which would otherwise be impartedto the vehicle body in traveling over rough roads, it will be ob viousthat the engine of the vehicle is protected against injury and its lifematerially prolonged. As solid rubber tires may be employed, it will befurther appreciated that the expense incident to the use of pneumaticwheel tires is avoided.

While I have shown and described the preferred construction andarrangements of the several elements employed, it will be understoodthat the invention is susceptible of considerable modification therein,without necessarily departing from the essential features or sacrificingany of the advantages thereof.

What I claim, is:

The combination with a wheel rim and hub, said hub embodying spacedflanges provided in their outer marginal portions with a plurality ofnotches, of a plurality of curved spring plates extending between therim and hub and fixed at their outer extremities to said rim, the innerextremities of such plates being angularly disposed to afford straightportions, the lower portion of such straight extremities being reducedto fit between the flanges of the hub, the wider portions of suchextremities being insertible within the notches of the flanges, suchstraight extremities being disposed a distance beyond the periphery ofthe flanges, and fastening means engageable with the flanges of the huband the spokes for maintaining the same in operative rela:

'tion, the straight portion of each of said spring plates being radiallyalined when in assembled position with a point of engagement of theouter extremity of such plate with the rim, such outer end of suchstraight portion terminating in close proximity with the periphery ofthe hub and serving as a point of flexure.
